Patented Sept. 10, 1907.

Application filed March '7, 1903. Serial No. 146,626.

To all whom it may concern:

Be it known that We, JOHN REICHERT and CHARLES S. BEEBE, citizens of theUnited States, residing at Racine, Racine county, Wisconsin, haveinvented certain new and useful Improvements in Tank-Lugs; and we dohereby declare the following to bea full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This inventionv relates to certain improvements in fastening andcoupling devices for uniting the ends of hoops or bands and tighteningthe same, and the invention is more 'particularly related toimprovements in tank lugs.

An object of the invention is to provide'an improved tank lug orcoupling and tightening device exceedingly simple and durable inconstruction which can be produced at a low price and to which the bandends can be easily and quickly attached, or detached if need be, Withoutthe employment of clamping grips or wedges.

Another object of the invention is to provide an improved tank lugexce'edingly simple and durable in construction and which can be easilyproduced at a minimum expense preferably by casting the lug in a singlepiece without the employment of a core in the mold during the castingoperation.

The invention consists in certain novel features in construction, incombinations and in arrangements of parts as more fully and particularlypointed out and described hereinafter.

Referring to the accompanying drawings, showing constructions merely asexamples for the purposes of explanation of devices among others withinthe spirit and scope of the invention ,-Figure l, is a plan View of thecoupling and fastening device applied, a portion of a tank being shownin cross section, and portions only of the hoops or bands being shown.Fig. 2, is a detail elevation of one of the tank lugs, castings or headsdetached. Fig. 3, is a longitudinal` section through one of said lugs orheads and the band end attached thereto, the coupling bolt not beingshown. Fig'. 4, is a cross section through ahead and the band end taken,on a complete head and band, in the plane of the line 4 4, Fig. 3. Fig.5, is a detail bottom plan view of one oi the lugs or heads detached.Fig. 6, is a detail cross section of a lug or head taken in the plane ofthe dotted line GHG, Fig. 3. Fig. 7, is a detail longitudinal sectionthrough one of the lugs or heads, the band end not. being shown, thesection being taken in the same plane as that of Fig. 3, the stop beingin the form of a continuous biidge piece instead of two fingers as shownin Figs. 2 and 3. Fig. 7, is a cross section through the form of lughaving the continuous bridge piece, taken in the plane of the line 7-7a,Fig. 7. Fig. 8, is an .elevation of a coupling and fastening devicediffering somewhat in construction from the -devices appearing inpreceding views, a portion of the tank being shown in elevation with theband ends united by said coupling and fastening device. Fig. 9, is alongitudinal section through the coupling and fastening device of Fig.8, a portion of the tank being shown in cross section. Fig. 10, is across section through the band and one of the heads or lugs, taken onthe plane of the line 10-10, Fig.v 9. Fig. 11, is a detail section inthe plane of the line 11-11, Fig. 8. Fig. 12, is a detail section of asingle coupling bolt lug without the studs and stop fingers of precedingviews.

In the drawings 1, is a tank or vessel built up of staves or sections.

2, is a flat metal band encircling said tank and provided with means forfastening itsends and by which the band can be adjusted or tightenedaround the tank. Said means comprise two heads, lugs or fasteningsattached to the band ends and united or connected by one or morecoupling and adjusting bolts or rods.

Each head, in the specific example shown, is formed in one piece ofmetal, such as a casting, and comprises a flat base portion 3, having afiat longitudinal seat to receive the iiat end portion of the hoop orband and formed with the side or edge stops or walls 4, along thelongitudinal side edges of the band end.

The base, along and intermediate the length and breadth of this seat isprovided with one or more rigid outwardly projecting pins or studs 5,integral with the base, although all forms of our invention are notlimited thereto. These studs can be variously shaped although I showeach cylindrical in form.

The head or lug extends longitudinally from the inner end of said seator base portion usually in the forni of an open frame or loop open atthe center in inward continuation of said longitudinal seat and formedby the side walls 6, 6, and the upwardly arched inner end or bridge 7,between said side walls and having the opening 8, therethrough for thecoupling bolt 9. The coupling bolt or rod 9, extends between the pair ofheads and through the openings 8, in the end pieces or bridges, and thenuts 10, 10, on the screw threaded ends ofthe bolt screw up to and abutagainst the upper outer faces of said end pieces in drawing the twoheads toward each other in tightening and fastening the band.

The open frame of each head or lug is recessed as shown to receive thenut 10, and permit free rotation thereof and to permit free access ofthe wrench or other tool for grasping and turning the nut. The loweredges of the said open frame are formed to seat and bear against thesurface of the tank, although usually the inner face or edge of the endpiece or bridge is recessed to permit passage thereunder of theprojecting end of the band.

We do not wish to so limit the invention to such a recess but the bandend may extend from the longitudinal seat of the fiat base across theopen center of said frame otherwise confined to or on the seat.

and under the said end bridge through the recess therein. Also as atpresent advised, we do not wish to limit the invention to forming the[iat base with an inwardly projecting frame to receive the coupling boltand nut.

The band end is adapted to rest flat down on the said seat, and the bandis formed with perforations 11, to receive the studs hereinbeforementioned. These studs are preferably of a length which is greater thanthe thickness of the band so that the studs will extend through andproject a distance beyond the outer face of the band. These holes can beeasily formed at the desired points in the length of the band at thelocations where the bands are being applied,and it is not necessary thatthe bands be accurately prepared in the shop for application to eachparticular tank.

The studs are of sufficient strength to withstand the strain exertedthereon by the bands when tightened, and we provide means to hold thebands down to the seats and against outward movement from or off thestuds. For instance, we can provide each head with means locatedoutwardly beyond the inner end of the said seat, to extend over or atthe outer face of the band end and prevent outward movement thereoftending to permit the band to slip from the studs or to hold the banddown on the seat, or limit movement thereon even though the studs arenot employed and the band is In other words, each head can be formed orprovided with one or more rigid stops under which the band end passes tohold the band on the studs.

The stop can be formed by an elevated cross or bridge piece 12 formedintegral with the lug, see Figs. 7, 7, and arranged transversely thereofto extend completely across the outer face of the band located on theseat of the base. The cross piece 12, is elevated above the plane of theband seat and above an opening therethrough and beyond an end edgethereof, so as to serve as a stop across the outer face of a band onsaid seat whether said band is secured 'by the studs or is otherwisecoupled to the lug and confined on the seat.

In applying the head or lug, it will be first tilted and slipped ontothe band end so that the band passes at an angle between the end of thebase and under the stop 12 the lug can then be tilted or rocked to itsnormal position against the tank which will bring the band against thefiat base and the studs projecting through the holes in the band, seeFigs. 1 and 3.

1f desired, the stop can be in the form of inwardly projectingtransverse fingers 13, 13, see Figs. 2, 3, 4, 5, in the same transverseplane as the stop 12, of Fig. 7.

On the second sheet of the drawings, we show the invention adapted to acoupling device employing two parallel coupling bolts 14, 14, with screwthreaded ends carrying nuts 15, 15. In this last named construction, thefiat base portion, with its seat and studs, is practically the same aspreviously described, but the open end frame is not employed. Instead ofsaid open end frame, the outer end of the base is provided or formedwith the lateral and forwardly extending enlargements or extensions 16,at their` outer ends having the upwardly projecting eyes receive thecoupling bolts and each formed by the outer web 7, and the inner web 7.

The stops 18, 18, extend inwardly from said eyes forwardly beyond thefront inner end of the said flat base or seat. These stops perform thesame function as in the construction of Sheet 1 and if desired can be inthe form of a bridge piece as in Fig. 7.

1n Fig. 12, we show the lug formed with the at base and having the seat3, with edge stops or walls 4/ but having transverse holes 19, toreceive bolts or rivets for securing the band to the lug instead of thestuds 5, of preceding views. In said Fig. .l2 we have also omitted thestops under which the band end slips, as the rivets or bolts passingthrough the band and lug will hold the band down in its seat.

Each coupling bolt eye, in the various constructions shown, is lformedby two arches, cross webs or bridges vizi-an inner web or arch 7 and anouter web or arch 7, and these webs are arranged in different lyetadjacent transverse planes. The outer web is arched up wardly oroutwardly and at its inner edge is rounded to receive the bolt, and theinner web is rounded or recessed at its outer edge to receive thecoupling bolt. The coupling bolt passes under the outer web and over theinner web, but the outer web engages said bolt to one side of the planeof the inner web.

The lug or casting is entirely open beneath the outer web or arch and isentirely open above the inner web or arch. By means of this arrangementin connection with the formation of the base plate and end open frame orside enlargements, each lug can be cast without a core and by theemployment of a plain mold and a device of great strength is produced byreason of the peculiar formation of each coupling bolt eye, as well asby the other features in the formation of the lug or casting.

The bands can be readily and quickly applied to the heads or lugs and ifdesired, the heads can be readily removed from the bands when it isdesired to place new bands on a tank.

The devices are exceedingly strong and durable and can be manufacturedand sold at alow price, and dispense with the employment of loose orextra grips or clamps.
